AI Technical Summary

Technical Problem

In existing technologies, the clearance between the centrifugal compressor's annulus and impeller is small, making it easy to damage the impeller during disassembly. Furthermore, the limited operating space makes disassembly and assembly inconvenient, and existing hoisting solutions are inefficient.

Method used

It adopts a manual hydraulic forklift and fork arm structure, and connects to the molded ring through the molded ring support. It utilizes the lifting and translating functions of the forklift to achieve stable disassembly and installation of the molded ring, avoiding contact with the impeller, and is compatible with molded rings of different specifications.

Benefits of technology

It enables safe and efficient disassembly and installation of the impeller ring, protects the impeller, adapts to different operating sites, and improves disassembly and assembly efficiency and stability.

Abstract

This utility model relates to the field of steam compressor technology and discloses an auxiliary device for assembling a centrifugal compressor's molding ring. It includes a pair of forks and a lifting frame of a manual hydraulic forklift. The forks are slidably connected to the lifting frame, and a molding ring support is connected to each fork. The molding ring is connected to the molding ring support by a first screw. When disassembly is required, the lifting frame can drive the forks to rise and fall, allowing the forks to slide on the lifting frame, thereby moving the molding ring support to the corresponding position on the molding ring. Then, the first screw 3 is used to fix the molding ring 9 to the molding ring support. The manual hydraulic forklift can then be moved to disassemble the molding ring. During disassembly, the molding ring will not come into contact with the impeller, effectively protecting the impeller. The disassembly process is simple, efficient, stable, and safe.
